Question

Write each compound inequality without using and.
1. a > 2 and a < 7

If possible, could I know what the directions is asking for and the steps? Thanks

Answer 1

turn the first one around
a>2 ----> 2<a

then 2 < a < 7

(usually we have the smaller numbers on the left and the larger on the right, which of course means we could have < in our statement)

Answer 2

Could you check to see if I did the next one correctly?
2.z < 0 and z > -6

-6 < z < 0

Answer 3

good job
